The last models in the Amstrad CPC range were the [[Plus|Amstrad 464 Plus]] and [[Plus|Amstrad 6128 Plus]], launched together in 1990. The CPC name is said to have been dropped because of a legal dispute with a French firm, though it is also likely that "CPC 6128 Plus" was considered too unwieldy a name and one redolent of the machine's mid-80s heritage.

The Plus series were mostly quite (but not quite 100%) compatible with the original CPC computers.The compatibility issues came mostly from:* The new Amstrad ROMs, breaking ROM access to the floppy drive* The emulated PPI chip, making the keyboard unresponsive* The emulated CRTC, breaking CPC demos
The Plus series incorporated a list of [[ASIC|new features]], like a cartridge port for instant program loading, DMA for the [[AY]] soundchip, enhanced hardware scrolling, programmable interrupts, 16 hardware zoomable sprites (not vectorized) with an independent palette of 15 colours, and a choice of 4096 colours all in a new, sleek case which mimicked the keyboard-computer design that was ''en vogue'' in the 16-bit market (ST, Amiga etc).
